Starter kit for dual mode Bluetooth development

The BMSKTOPASM369BT starter kit by Toshiba Electronics Europe makes it possible to evaluate the Bluetooth Dual Mode LSI TC35661-5xx in combination with a CortexM3 MCU as host MCU. It is built to execute Bluetooth driver software and debug user application code via an embedded J-Link debugger interface.

The starter kit is designed to get users of the Chiron-501 dual mode Bluetooth IC up and running with their designs. The starter kit is based around a Panasonic PAN1026 module featuring an embedded Chiron-501 IC with dual mode Bluetooth protocol stack and profiles. It consists of a Topas369BT board, a Segger J-Link JTAG/SWD emulator with USB interface, a J-Link 19-pin Cortex-M adapter, a USB cable, and a apid Start-up guide.

The Chiron-501 IC includes a TMPM369 ARM Cortex-M3 based MCU with 512 KiB flash memory. The embedded dual mode software has a Serial Port Profile and Bluetooth Low Energy (BLE) Generic Attribute Profile GATT API for device set up, connection, and data transfer. A high-level driver layer allows access to the function set of the Bluetooth IC. Provided are application examples that can be compiled to run on the MCU with Free-RTOSTM integration (the OS itself is available from Real Time Engineers Ltd). The application software includes a set of BLE reference profiles and a design guide on how to develop proprietary BLE profiles. A J-Link JTAG debugger interface incorporated in the starter kit board is compatible with third party tool-chains such as those from Atollic, IAR and Keil. The embedded MCU also supports interfaces on the board for CAN connection and others.

Compliant with Bluetooth version 4.0, the IC can support both classic Bluetooth and Low Energy communication methods. The classic Bluetooth communication method enables serial communication with a range of devices such as smartphones, laptops and other Bluetooth peripherals, while the low energy “Bluetooth Smart” method reduces power consumption and shortens connection set up time. It is designed for portable peripheral devices such as temperature meters, remote switches and controls or various sensors. The two Bluetooth communication methods are not interoperable and require different device applications to match the communication method of the host appliance. By incorporating both the Serial Port Profile (SPP) that is used for classic communication and the Generic Attribute Profile (GATT) used for Low Energy communication into a single IC, the device contributes to component reduction and development efficiency efforts. The inclusion of the SPP and GATT profiles on-chip also reduces loads on external micro-controllers and simplifies the Bluetooth certification process.
